Plaque-like erythema with milia: a noninfectious dermal mucinosis mimicking cryptococcal cellulitis in a renal transplant recipient.

Cellulitis of the skin is most commonly a bacterial infection caused by either staphylococcal or streptococcal species. However, in immunocompromised patients, cellulitis may be a harbinger of more ominous disease. In these patients, rapid clinical diagnosis and treatment is necessary.

Contact sensitization to cyanoacrylate adhesive as a cause of severe onychodystrophy.

Background: The technology used for artificial nails, the chemistry of cyanoacrylates and the reported reactions to these products are briefly reviewed.

Materials And Methods: We studied three patients with prominent fingernail dystrophy, nail bed hyperkeratosis, fingertip eczema, and onycholysis, two of whom also had eczematous lesions at distant sites, ostensibly from hand transfer. Patch testing was performed with a standard screening tray, dried cyanoacrylate adhesives, and, in one case, with fingernail clippings.

Oculocerebral dysgenesis in the linear nevus sebaceous syndrome.

Purpose: The authors document the association of peripapillary staphyloma and an atypical variant of hemimegalencephaly with the linear nevus sebaceous syndrome.

Background: Linear nevus sebaceous syndrome is an uncommon neurocutaneous disorder that has a propensity to involve the eyes.

Methods: Clinical, histopathologic, and neuroimaging findings are examined in a child with linear nevus sebaceous syndrome.

Metastatic cutaneous squamous cell carcinoma derived from actinic keratosis.

Background: Squamous cell carcinoma (SCC) with histologically contiguous actinic keratosis has long been thought of as a tumor with minimal risk for metastasis. The objective of this study was to determine if contiguous actinic keratosis is present in the original tumors of metastatic cutaneous SCC and to describe the histologic features of these tumors.

Methods: The primary lesions of 22 patients with metastatic cutaneous SCC were examined using light microscopy.

Cutaneous eruption of lymphocyte recovery mimicking mycosis fungoides in a patient with acute myelocytic leukemia.

Eruption of lymphocyte recovery (ELR) develops in the setting of leukocyte reconstitution after iatrogenic marrow aplasia and displays a superficial perivascular lymphocytic infiltrate composed of CD3+/CD4+ cells. Epidermal changes are usually minimal to absent. We report a case of an ELR mimicking mycosis fungoides with the formation of CD4+ Pautrier-like microabscesses.

Lymphoepithelioma-like carcinoma of the skin treated by Mohs micrographic surgery.

Background: Lymphoepithelioma-like carcinoma of the skin (LELCS) is a rare malignant tumor thought to be of adnexal origin. Because of its rarity, treatment parameters have not been defined.

Objective: To examine the role and success of Mohs micrographic surgery in the treatment of LELCS versus other forms of treatment previously documented in the literature.

Stiffness changes in chick hair bundles following in vitro overstimulation.

1. The in vitro effect of intense stimulation on the micromechanical stiffness of hair cell sensory hair bundles was studied at three locations on the chick basilar papilla. Threshold levels of hair bundle motion, produced by a water jet stimulus, were examined before and after exposure to a 300 Hz water jet stimulus set at 25 dB above the pre-exposure threshold level.
